Disable ThreadFuzzer in non-server binaries of ClickHouse by default.
Why it matters
ThreadFuzzer is a tool used to detect concurrency issues by introducing thread scheduling delays. However, it is primarily useful for server binaries where concurrent execution is critical. Disabling ThreadFuzzer by default in non-server binaries reduces unnecessary overhead and avoids unintended interference in those binaries, improving their stability and performance.How to use it
This change automatically disables ThreadFuzzer in all non-server ClickHouse binaries by default, so no additional configuration is needed for users. For server binaries, ThreadFuzzer remains enabled unless explicitly disabled.
